Read object from I/O buffer.
A typical use for this function is:

I.e. clCast should point to a TClass object describing the class pointed to by your pointer. In case of multiple inheritance, the return value might not be the real beginning of the object in memory. You will need to use a dynamic_cast later if you need to retrieve it.

Write a Double32_t to the buffer.
The following cases are supported for streaming a Double32_t type depending on the range declaration in the comment field of the data member:
| Case | Example |
|---|---|
| A | Double32_t fNormal; |
| B | Double32_t fTemperature; //[0,100] |
| C | Double32_t fCharge; //[-1,1,2] |
| D | Double32_t fVertex[3]; //[-30,30,10] |
| E | Double32_t fChi2; //[0,0,6] |
| F | Int_t fNsp; Double32_t* fPointValue; //[fNsp][0,3] |
In case A fNormal is converted from a Double_t to a Float_t In case B fTemperature is converted to a 32 bit unsigned integer In case C fCharge is converted to a 2 bits unsigned integer In case D the array elements of fVertex are converted to an unsigned 10 bits integer In case E fChi2 is converted to a Float_t with mantissa truncated precision at 6 bits In case F the fNsp elements of array fPointvalue are converted to an unsigned 32 bit integer Note that the range specifier must follow the dimension specifier. Case B has more precision (9 to 10 significative digits than case A (6 to 7 digits). See TBufferFile::WriteFloat16 for more information.

Write a Float16_t to the buffer.
The following cases are supported for streaming a Float16_t type depending on the range declaration in the comment field of the data member:
| Case | Example |
|---|---|
| A | Float16_t fNormal; |
| B | Float16_t fTemperature; //[0,100] |
| C | Float16_t fCharge; //[-1,1,2] |
| D | Float16_t fVertex[3]; //[-30,30,10] |
| E | Float16_t fChi2; //[0,0,6] |
| F | Int_t fNsp; Float16_t* fPointValue; //[fNsp][0,3] |
The range specifier has the general format: [xmin,xmax] or [xmin,xmax,nbits]
Lets assume an original variable float x: When using the format [0,0,8] (ie range not specified) you get the best relative precision when storing and reading back the truncated x, say xt. The variance of (x-xt)/x will be better than when specifying a range for the same number of bits. However the precision relative to the range (x-xt)/(xmax-xmin) will be worst, and vice-versa. The format [0,0,8] is also interesting when the range of x is infinite or unknown.
It is important to understand the difference with the meaning of nbits

Write object to I/O buffer.
This function assumes that the value of 'actualObjectStart' is the actual start of the object of class 'actualClass' If 'cacheReuse' is true (default) upon seeing an object address a second time, we record the offset where its was written the first time rather than streaming the object a second time. If 'cacheReuse' is false, we always stream the object. This allows the (re)use of temporary object to store different data in the same buffer.
